How do I create an app that takes a photo and displays the colour of a predefined colour in my database

Hi guys,

Newbie to with a little bit of coding experience.

I am trying to create an app that allows the user to take a photo via it’s native camera on thier phone and then convert it into a predefined colour that I have defined in a database via hex codes and present it as a answer e.g the person takes a photo of a pot and my app will process and state that it is bremadent blue, then the user can share it natively on thier phone or via email with that answer. Also I need to delete the image from the server afterwards so it’s only used once.

So far I have placed a picture upload element and installed a colour picker plugin, I have tried to look online and there doesnt seem to be an answer.

Any help much appreciated
